The extent of your own contribution is being expressed with the term "Loan-to-Value Percentage (LTV)":
this is the relationship, in percentage, between the requested loan amount and the appraised value of the property.
The flexibility of your loan is being expressed with the term "Variability":
this is the number of years it takes before your interest rate can be adjusted to the, at that moment, present market conditions
... fixed-rate! They all cry out immediately. We don't fully agree this statement.
Often we can offer you a 1-1-1 or even a 3-3-3 within a formula interest rate cap 2% and without a downward limitation.
In other words, the interest rate of such a mortgage loan can increase with a maximum of 2% with regard to the initial interest rate.
So this formula is, even in a worst-case scenario, hardly more expensive than the fixed-rate loan of for example 20 years.
Moreover we also noticed that interest rates hardly changed over the last 5 years, and on the contrary even decreased a little.
We also noticed that financial institutions are not free to change the interest rate but have to follow a certain mechanism, laid down by the law. The adaptation of such interest rates is joint to the linear debentures of the state at 1 or 3 years (the so-called index). It is very simple: if the index falls with one percent, your interest rate will do the same and vice versa.
In brief, it is certainly worth while to weigh the pros and cons but a fixed-rate mortgage loan is, given the present historical low interest rates, certainly an excellent choice.
